This chapter provides information on plug-in connector blocks and 
field wiring (ANIN and PRT signals) for the I/O, Prover, and HART 
modules. This chapter also discussed the optional pulse-counting 
mezzanine module (P148) which fits as a daughterboard on either the 
I/O or Prover module.   
 
Failure to exercise proper electrostatic discharge precautions (such as 
wearing a grounded wrist strap) when accessing the back of the unit or 
when handling CPU or I/O modules may reset the processor or damage 
electronic components, resulting in interrupted operations 
 
4.1  I/O Module (P144) 
The I/O module (P144) measures process signals the CPU uses while 
running the flow computer functions. The module provides 12 
analogue inputs (AI), 4 analogue outputs (AO), 16 digital inputs (DI) , 
12 digital outputs (DO), 4 pulse inputs (PI), 5 pulse outputs (PO), 3 
frequency (density) inputs, and 3 PRT/RTD inputs. Refer to Figure 4-2 
for the I/O module terminations.
